Croatia achieved iodine sufficiency in schoolchildren six years after salt iodination regulations. Urinary iodine levels significantly improved, indicating successful public health intervention for iodine intake.

Area of Science:

  • Public Health
  • Endocrinology
  • Nutrition Science

Background:

  • Iodine deficiency disorders (IDD) pose a significant global health challenge.
  • Salt iodination is a primary strategy for IDD prevention.
  • Croatia implemented salt iodination regulations in 1996.

Purpose of the Study:

  • To assess the impact of salt iodination on iodine intake among Croatian schoolchildren.
  • To evaluate thyroid volume and urinary iodine excretion in the target population.
  • To determine if iodine sufficiency has been achieved post-regulation.

Main Methods:

  • A cross-sectional study involving 927 schoolchildren (aged 6-12) across four Croatian regions.
  • Sonographic measurement of thyroid volume.
  • Analysis of urinary iodine excretion (UIE) medians.

  • Quality control of iodized salt from production to consumption.

    • Main Results:

    • Thyroid volumes were within normal ranges for iodine-replete children.
    • Significant increases in median UIE were observed across all studied regions between 1991-2002.
    • Overall median UIE reached 14.0 microg/dl, indicating iodine sufficiency.
    • Croatian salt was confirmed to be adequately iodized.

    Conclusions:

    • The salt iodination program in Croatia has successfully improved iodine intake and achieved iodine sufficiency in schoolchildren.
    • Public health initiatives targeting salt iodination are effective in addressing iodine deficiency.
    • Continued monitoring is recommended to maintain iodine sufficiency.
